A formula for the curvature of the graph of a function in the xy-plane a. The graph y = f(a) in the xy-plane automatically has the parametrization x = x, y = f(x ), and the vector formula r(x) = ai + f(a)j. Use this formula to show that if f is a twice- differentiable function of x, then = 686 / 17-31 > Q N 9 P W O 12:11 PM 9/24/2024
